Electrochemical Degradation Pathway of Tricyclazole in Aqueous Solution Using Lead Dioxide Anode

The electrochemical degradation of tricyclazole (TC) in aqueous solution on Ti/SnO2Sb/PbO2anodes was investigated. The degradation efficiency and mineralization rate was studied. Kinetic analyses indicated that the electrochemical degradation followed a pseudo-first-order reaction. The mineralization intermediates were analyzed by chromatographic techniques. Finally, a pathway for electrochemical degradation of TC in aqueous medium was proposed.

Electrocatalytic Degradation of Cellulose Using Lead Dioxide Anode

A novel method of cellulose degradation is investigated in this paper. In this work, a three-electrode system, which contains a Pb/PbO2 anode, two copper cathodes and a reference saturated calomel electrode (SCE), is applied to electrocatalytic degradation of cellulose. The composition of the products in filtrate is characterized by phenol-sulfuric acid method, NMR and GC-MS. In addition, the solid sample is analyzed via Ubbelohde capillary viscometer and FT-IR spectra. The results suggest that it is effective to convert cellulose to soluble sugar, 5-hydroxymethylfurfural (5-HMF) and other products by electrocatalytic method. The reaction mechanism of cellulose degradation is also discussed.
